["Jonathan P" <jpilling@xxxxxxxxxxxx>]

Hi there,

Details:

PHP Version: 5.3.0beta 1
OS: zLinux - SLES 10 s390x 64bit

Description:

../configure --disable-all --disable-debug results in a segmentation fault on 
'make test':

However ./configure --disable-all --enable-debug results in an OK 'make 
test' and 'make install'.

Can anyone help me figure out why PHP is giving the segmentation error when 
I use the --disable-debug option?
I require PHP to be configured with the --disable-debug option.
Any help is much appreciated.

kind regards.
